"IB AA HL is one of the hardest pre-university mathematics courses in the world. Every student who takes it deserves a mathematician — not a workaround."— Dr. Ritukar Chadha, PhD (Maths), M.Sc (Maths) · Founder, R. Chadha IB Maths
Sydney's IB cohort is highly motivated and increasingly ambitious in university aspirations — targeting the University of Sydney, UNSW, and institutions overseas. The depth demanded by AA HL, in particular, requires a mathematician's approach rather than an exam-coaching approach.
Sydney students frequently target University of Sydney, UNSW, ANU, and international universities in the UK and US.
Dr. Chadha's platform serves IB AA students from every international school in Sydney. The same depth of preparation — regardless of which school you attend.
Two routes — the self-paced digital course, and premium 1:1 coaching. Both built on the same R. Chadha Signature Model. All sessions conducted online. Time zone: AEDT / AEST.
The complete AA HL course — every topic from first principles, built on 28 years of university mathematics teaching and 10 advanced textbooks.

"I do not teach students what to write. I teach them to understand — so deeply that no question can surprise them."— Dr. Ritukar Chadha, PhD (Maths), M.Sc (Maths)
"I was doing AA HL at a Sydney school with excellent teachers — but something was missing. Dr. Chadha's Signature Model gave me the conceptual depth I needed for Paper 3."
